Product Overview
This Specpure® Rhenium plasma standard solution delivers 1000µg/ml concentration in a high-purity aqueous matrix, specifically formulated for demanding spectroscopic applications where traceability and minimal interference are critical. The solution is prepared using Specpure® grade rhenium (99.999% trace metal basis) dissolved in ultra-pure nitric acid, ensuring exceptional stability and compatibility with plasma-based instrumentation. Its low matrix background eliminates spectral overlaps, making it ideal for creating calibration curves in ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS) workflows. The solution undergoes rigorous multi-point quality control, including ICP-OES verification against NIST-traceable standards, with certification provided for each batch. Packaged in HDPE bottles with tamper-evident seals, the solution maintains integrity during storage and transport. The 1000µg/ml concentration allows for precise serial dilutions while minimizing volumetric errors, and the nitric acid matrix (2-5% v/v) prevents precipitation or adsorption losses. Compatible with most autosampler systems, this standard solution reduces preparation time while improving analytical reproducibility in research and industrial laboratories.
FAQs
1. What is the shelf life of this Specpure® Rhenium plasma standard solution when unopened?
The unopened solution remains stable for 24 months from the date of manufacture when stored at 15-25°C in its original packaging. Always verify the expiration date on the certificate of analysis.
2. Can this standard be used directly for ICP-MS analysis without further dilution?
While the 1000µg/ml concentration is suitable for some ICP-OES applications, ICP-MS typically requires dilution to ppb levels (1-100µg/L range) to avoid detector saturation and matrix effects from the nitric acid.
3. What material are the bottles made of, and are they compatible with organic solvents?
The bottles are manufactured from high-density polyethylene (HDPE), which is resistant to the nitric acid matrix but not recommended for long-term storage of organic solvents like acetone or hexane.
4. How does the Specpure® grade differ from standard analytical-grade rhenium solutions?
Specpure® grade undergoes additional purification steps to reduce trace metallic impurities below 10 ppb for most elements, with certified limits for over 70 potential contaminants, unlike standard grades that may contain ppm-level impurities.
5. Is a safety data sheet (SDS) provided with this product?
Yes, a comprehensive SDS is included with each shipment, detailing handling precautions, first-aid measures, and disposal guidelines specific to the nitric acid matrix and rhenium content.
